From 2011 to 2020, the 1.2-liter Nissan HR12DDR or 1.2 DIG-S engine was manufactured in Japan and fitted to charged versions of well-known models like the Note or Micra. This engine has an Eaton R410 compressor and runs on the Miller economy cycle.
HR10DDT, HRA2DDT, HR12DE, HR13DDT, HR15DE, and HR16DE are members of the HR family.
The engine was mounted on:
- Nissan Micra 4 (K13) in 2011 – 2017;
- Nissan Note 2 (E12) in 2012 – 2020.

Disadvantages of the HR12DDR engine
The primary grievances on the forums are about vibrations and noise, but this motor is dependable;
If the lubricant is changed, the compressor can run for a long time, but occasionally its pipe bursts; intake valves rapidly fill with soot, just like in all direct-injection engines;
The catalyst, mass air flow sensor, and ignition unit relay are additional weak points of the apparatus;
There are no hydraulic lifters here, so remember to adjust the valves’ thermal clearance.
